Filter by:The prone maneuver is a well-established therapy in ARDS. Traditionally, the maneuver is perform with thoraco-abdominal cushions. The goal of this study is assess, using electrical impedance tomography, whether the arrangement mode of the cushions alters lung recruitment during the prone maneuver in patients with moderate to severe ARDS.
Patients with ARDS often suffer a gravity-dependent alveolar collapse, resulting in a reduction of tidal volume, residual alveolar excessive distension, and ventilator-related lung injury(VILI) induced by unreasonable ventilator setting.Prone ventilation (PPV) improves the gravity-dependent alveolar ventilation and promotes lung recruitment in the gravity-dependent area and improves lung compliance. Previous studies showed that prolonged PPV combined with low tidal volume(LTV) lung protected ventilation can significantly reduce the mortality of patients with moderate to severe ARDS.Although more than 60% of patients with moderate to severe ARDS due to COVID-19 has been widely implemented PPV,studies showed an improvement in oxygenation in patients with ARDS(the P/F radio improved by more than 20% before and after PPV) was 9-77%, that is, That is, some patients are unresponsive to PPV. In addition, some patients showed CO2 responsiveness after PPV(ventilation rate (VR) decreased significantly after PPV).The tools for monitoring the effects of PPV on ventilation and blood flow at bedside are still lacking, Electrical impedance tomography (EIT) is a non-invasive, non-radiative, real-time bedside lung imaging technique that can monitor local lung ventilation distribution. This study intends to use EIT to evaluate pulmonary ventilation, blood flow distribution and local V/Q ratio before and after PPV, as well as to monitor the changes in pulmonary physiology before and after PPV, explore the mechanism of PPV improving oxygenation by combined with the changes in oxygenation, and explore the factors that predict and affect PPV responsiveness.
The goal of this pilot interventional no-profit study is to evaluate airway pressure, esophageal pressure and variations in lung volume distribution with EIT in mechanically ventilated patients admitted to our UTI with respiratory failure after the application of an abdominal weight and resulting increase of intra-abdominal pressure.
Acute Respiratory Distress Syndrome (ARDS), marked by acute hypoxemia and bilateral pulmonary infiltrates, has undergone multiple definitions over the years. Challenges persist regarding the ARDS definitions, leading to various revisions. Through the Delphi study, the investigators aims to gather global opinions on the conceptual framework of ARDS, assess the utility of current and past definitions, and explore the role of subphenotyping. The diverse panel's collective expertise will contribute valuable insights for refining future ARDS definitions and enhancing clinical management.
The goal of this prospective observational study is to describe the incidence of reverse trigger (RT) in mechanically ventilated patients with diagnosis of acute respiratory distress syndrome (ARDS). The main questions it aims to answer are: - Real incidence of RT based on continuous monitoring - The response to mechanical ventilatiory adjustments Participants will be included as soon as neuromuscular blockers (NMB)/sedation is stopped or in case of spontaneous respiratory efforts detection, whatever happens first. Continuous monitoring will be performed by esophageal manometry until switch to a pressure support (spontaneous) mode, restart of deep sedation/neuromuscular blockers by medical indication, or death. In order to allow detection of possible RT in patients with ongoing sedation/NMB, mechanical ventilator waveforms will be screened every 1-2 hours by investigators and critical care physicians with at least 1 year of specific training in detection of dyssynchronies.
The goal of this observational study is to compare pulmonary health parameter measurements from the VQm PHM™ to existing clinical measurements. The main questions it aims to answer are: - Confirm the performance of non-invasive pulmonary health parameter shunt fraction value found on the VQm PHM™ when compared to available reference measurements. - Confirm the performance of non-invasive pulmonary health parameter pulmonary blood flow, functional residual capacity and physiological dead space found on the VQm PHM™ when compared to available reference measurements.
The goal of this observational study is to determine the relationship between the nutritional profile of critically ill patients diagnosed with COVID-19 and disease severity, prognosis, and survival, to assess the ability to meet nutritional goals, EN complications, and reasons for discontinuation and postponement of feeding. The main questions aim to answer are the relationship between the duration of EN initiation and Prognostic Nutritional Index (PNI) score, neutrophil-lymphocyte ratio (NLR), oxygenation status, MV, ICU, and length of hospital stay, overall mortality, and whether nutritional goals were met, EN complications, and reasons for discontinuation and postponement.
The purpose of the trial is to study the tolerability, safety and pharmacokinetics of the study drug with participation of healthy volunteers after single intravenous administration with dose escalation (0.03 mg/kg, 0.06 mg/kg and 0.12 mg/kg). Before administration the study drug will be dosed and diluted in 200 ml of isotonic solution of 0.9% sodium chloride, and then will be administered once intravenously via infusion. During the entire follow-up period, the effect of the study drug on vital signs, instrumental and laboratory data, the development, severity and association of adverse events with the study drug will be monitored, investigated and studied.
1. Construct a structured clinical data and biosample information platform for Chinese patients with acute lung injury/ acute respiratory distress syndrome. 2. By deciphering the heterogeneity of patients with acute lung injury/ acute respiratory distress syndrome, achieve clinical, longitudinal physiological, and biological sub-phenotyping to guide individualized precision treatment and improve prognosis.
This mixed-methods study comprising a 3-arm pilot RCT and a qualitative study aims to investigate the preliminary effects and feasibility of a home-based combined activity and cognitive intervention for ICU survivors (COMBAT-ICU). Adopting a 3-arm design with COMBAT-ICU, exercise and attention placebo study arms will enable us to evaluate the added effects, if any, of the novel combined intervention compared with the standard exercise-only rehabilitation strategy and attention placebo. Data triangulation from quantitative and qualitative aspects can facilitate result interpretation. The study's objectives are: 1. To evaluate the preliminary effects of the COMBAT-ICU intervention for ICU survivors on PICS, physical, mental and cognitive outcomes, HRQoL, unplanned re-hospitalisation rate, and mortality. 2. To explore the feasibility and acceptability of the COMBAT-ICU intervention and ICU survivors' intervention engagement experience. The hypothesis of the first objective is that upon completion of the COMBAT-ICU intervention, ICU survivors will have reduced PICS, improved physical function, mental health, cognition and HRQoL, and reduced unplanned readmissions and mortality compared with the exercise and attention placebo groups at post-intervention and 3 months thereafter. While the hypothesis of the second objective is that the COMBAT-ICU intervention is feasible and acceptable for ICU survivors.
